Container for rapid charge accumulator having channels molded in the lid for distributing the electrolyte

Abstract

The invention discloses an accumulator container comprising a box (2) presenting one or more element-containing cells (3), each of said cells presenting at least one tube (5) for the inlet of the electrolyte. Said tube (5) has one end connected with an opening (6) made in the lid and its other end arranged near the bottom of the container. Said box presents a lid having at least one first inlet opening (6), connected through channels (71, 72, 73, 74, 75, 76) for the distribution of the electrolyte with electrolyte inletting tubes (5, 51), found in the box and in the lid, and at least one second outlet opening (11) connected with level tubes (81), each belonging to each cell.

I claim: 
     
       1. An accumulator container for receiving accumulator components therein formed of moldable plastic material adapted for rapid filling with a first charge of electrolyte, comprising: a box; and a lid, the box having an outer wall and at least one intermediate partition forming one or more cells for receiving the accumulator components to be immersed in the electrolyte, each of said cells having at least one inlet tube for receiving the first charge of electrolyte, and the lid having channels for communicating with each inlet tube, each of said tubes being arranged in a substantially vertical orientation, having an upper end communicating with the corresponding channel in the lid and a lower end arranged near the bottom of the box, said lid having at least one first inlet opening for each channel, commonly connected to the channels for the distribution of the electrolyte, and a level tube for each cell, each level tube having an inlet communicating with an upper end of the corresponding channel and at least one second outlet opening formed therein and commonly connected with the level tubes.   
     
     
       2. A container according to claim 1, wherein the lid has a thickness and said inlet tubes, said level tubes and said channels are molded within the thickness of said lid. 
     
     
       3. A container according to claim 1, wherein the channels for distribution of the electrolyte in the lid define a substantially equal course, beginning from the common opening to each inlet tube, said course ensuring essentially the same charge losses. 
     
     
       4. A container according to claim 1 further comprising at least one receptacle having a lower end communicating with said level tubes for refilling said accumulator. 
     
     
       5. A container according to claim 1 wherein the inlet tubes and channels are formed by means of molding thermoplastic material with a coinjection of nitrogen. 
     
     
       6. A container according to claim 1 wherein each cell has a corner portion and the inlet tubes are located in correspondence with the corner portion of each cell formed by the wall of the box and by the intermediate partition dividing each cell from the next. 
     
     
       7. A container according to claim 6, wherein each inlet tube is adjacent to the inlet tube of the next cell. 
     
     
       8. A container according to claim 1 wherein the lid has a lateral surface and further comprising a header connecting the level tubes said header having at least one end communicating with the lateral surface of the lid through a hole therein, and a cap for closing said hole. 
     
     
       9. A accumulator container formed of a moldable plastic material adapted for rapid filling with a first charge of electrolyte comprising: a box portion having external sidewalls, a bottom wall, and intermediate walls forming a plurality of cells therein, the box having an open top, each of said cells having integrally formed therein at least one inlet tube extending from the open top to near the bottom wall for receiving the first charge of electrolyte therethrough; and   a lid having marginal portions for engaging the open top of the box, the lid having a plurality of inlet channels one each for communicating with each of said inlet tubes, and an inlet commonly coupled to the inlet channels for distribution of the electrolyte thereto, the lid further including an outlet tube for communicating with an upper portion of each cell and a header tube commonly connecting the outlet tubes with a common outlet therefor.
